I often see people who write SQL like this:
SELECT * from TableA LEFT OUTER JOIN TableB ON (ID1=I2)
I myself write simply:
SELE
One thing that several months on Stackoverflow has shown me is how much SQL is written and / or maintained by people with no previous exposure to SQL or relational databases at all.
For that reason, I think that the more explicit you can be the better off the next programmer is going to be when looking at your code.
